Salient Pole Rotor
Given Below is the construction and advantages of the Salient Pole Rotor
Construction of the Salient Pole Rotor
- The core is made of hollow cylinder with stacked laminations of steel, to minimize eddy current losses.
- Salient poles project outwards from the core, thus the name- Salient Pole Rotor.
- Each salient pole has field winding wrapped around in it.
- A shaft connects core to the prime mover or the load and transmits the mechanical torque generated by the rotor.
Advantages of the Salient Pole Rotor
- Used in low and medium speed machines.
- Lower Windage losses.
- Delivers high starting torque.
- Offers improved power factor.
Salient Pole Rotor and Cylindrical Pole Rotor
Cylindrical Pole Rotor
Given Below is the construction and advantages of the Cylindrical Pole Rotor
Construction of Cylindrical Pole Rotor
- The core is made of solid steel cylinder forming a smooth, round shape.
- Parallel slots are observed along the outer surface of the cylinder, running lengthwise.
- These parallel slots contains rotor windings, which are copper conductors, insulating in nature.
- At ends of rotors, large end rings are connected, which are generally made of steel.
- The shaft connects the rotor core to external load to transmit generated torque.
Advantages of Cylindrical Pole Rotor
- Efficient operation at high speeds.
- Minimum air resistance or windage losses.
- Simpler construction and maintenance.
- Doesn’t require additional damper windings for stabilization.
What is Rotor?
Rotors are a fundamental part of electrical machines and play an important role in their operation. Rotor is the rotating part of an induction motor. It is connected to the mechanical load through the shaft. There are various designs of rotors available on the basis of application and type of machine, such as squirrel cage or wound type.
In this article we will go through the definition of the Rotor with its construction in detail with its diagram, we will also go through the classification of Rotors and difference between stator and rotor, At last we will conclude our article with some of its applications and FAQs.
